编写题解 1035: [编程入门]自定义函数之字符类型统计

解题思路:

注意事项:

参考代码:

#include <iostream>

using namespace std;

void a(string s)

{

    int sum1=0,sum2=0,sum3=0,sum4=0;

    for(int i ; i<s.size(); i++)

    {

        if(s[i]>='A'&&s[i]<='Z'||s[i]>='a'&&s[i]<='z')

            sum1++;

        else if(s[i]>='0'&&s[i]<='9')

            sum2++;

        else if(s[i]==' ')

            sum3++;

        else

            sum4++;

    }

    cout<<sum1<<' '<<sum2<<' '<<sum3<<' '<<sum4;

    return ;

}

int main()

{

    string s;

    getline(cin,s);

    a(s);

    return 0;

}
